Visiting Marigot in September

September weather

Marigot stays hot in September, with highs around 29°C and nights barely cooler. Humidity is high, and rain falls on many days, often in short, heavy showers. You'll still get sunny spells, but wet paths and sudden downpours can interrupt a day out.

The waterfront and shops in downtown Marigot work well between showers. Save Fort Louis for a clearer spell: its steep steps can get slippery when wet, and cloud can hide the view over the bay. Beach time is possible, but don't count on an unbroken sunny day.

Events and quiet days

September is part of the Atlantic hurricane season, so storms can affect flights and ferry services. There isn't a major annual Marigot festival to build a September trip around. The town feels quieter than during the December-to-April high season, when visitors come for drier weather.

If you hate crowds, you'll find more room around the market and waterfront. Prices for stays are often lower in this low season, though storm risk is the trade-off. Keep plans flexible, especially if you're taking a ferry from Marigot to Anguilla.

Make the most of your visit

Rainfall is lower than in October, but higher than in August. That makes September a changeable month, not a dry one. Choose short outings you can pause, rather than planning a full day outdoors. The Musée de Saint-Martin is a useful indoor stop when showers settle in.

Travelling with kids? Keep a rainy-day stop in downtown Marigot.

For a local tip, climb Fort Louis when the sky clears, then head down to the waterfront for a johnny cake, a fried local snack. Check ferry updates at the Marigot terminal before setting out; rough weather can disrupt crossings.
